Codeine

Codeine is a naturally occurring opioid alkaloid found in the opium poppy, Papaver somniferum.
It is commonly used as an analgesic, antitussive, and antidiarrheal medication.
Codeine acts as a mild sedative and can be effective in relieving pain, suppressing coughing, and treating diarrhea.
It is often combined with other medications, such as acetaminophen, to enhance its therapeutic effects.
Codeine is a Schedule II controlled substance in many countries due to its potential for abuse and addiction.
Proper dosage and medical supervision are essential when using codeine-containing products to ensure safe and effective use.

Using pharmacy claims data, we isolated prescriptions for fentanyl (patch or oral form), hydrocodone, hydromorphone (oral form), methadone, morphine, oxymorphone, and oxycodone and excluded prescriptions containing hydrocodone in cough/cold formulation. In addition, we excluded analgesic preparations containing codeine, such as acetaminophen/codeine combinations. Our outcome of interest was chronic opioid use within the first postsurgical year. Previous studies using administrative claims data have defined chronic opioid use as having filled 10 or more prescriptions or more than 120 days’ supply within a 1-year period.11 (link) Since some opioid use is likely expected in the immediate postoperative period, we slightly modified this definition to having filled 10 or more prescriptions or more than 120 days’ supply within the first year after surgery, excluding the first 90 postoperative days (ie, we measure only postoperative days 91–365).

The Ontario Drug Benefit database was used to ascertain opioid use after hospital discharge. These opioids included codeine, morphine, oxycodone, hydromorphone, meperidine, oxymorphone, methadone, and transdermal fentanyl. We also characterised these drugs by whether they were sustained release formulations. Early post-discharge opioid use was defined as one or more prescriptions for opioids within 1 to 90 days after surgery. Prolonged opioid use after hospital discharge was defined as one or more opioid prescriptions within 1 to 90 days after surgery along with one or more prescriptions for opioids within 91 to 180 days after surgery. This 90 day minimum interval for defining prolonged opioid use is more conservative than the 60 day interval used by the International Association for the Study of Pain to define persistent postsurgical pain,17 which has been criticised as being too short.18 (link)

Full reports of randomised controlled trials of oral paracetamol combined with codeine for acute postoperative pain were sought. Different search strategies were used to identify eligible reports in MEDLINE (1966 - March 2000), EMBASE (1980 - March 2000), the Cochrane Library (Issue 3, 2000) and the Oxford Pain Relief Database (1950 - 1994) [16 (link)]. Reference lists of retrieved reports and reviews [1 (link),2 ] were searched for additional trials. Abstracts, review articles and unpublished reports were not considered.
Criteria for inclusion for postoperative pain were: full journal publication, randomised controlled trials which included single dose treatment groups of oral paracetamol combined with codeine, double blind design, baseline postoperative pain of moderate to severe intensity, patients over 15 years of age, at least 10 patients per group, and the pain outcome measures of total pain relief (TOTPAR) or summed pain intensity difference (SPID) over 4-6 hours or sufficient data provided to allow their calculation. Pain measures allowed for the calculation of TOTPAR or SPID were a standard five point pain relief scale (none, slight, moderate, good, complete), a standard four point pain intensity scale (none, mild, moderate, severe) or a standard visual analogue scale (VAS) for pain relief or pain intensity. Each report was scored for quality using a three item, 1-5 score, quality scale [6 (link)].
For each trial, mean TOTPAR, SPID, VASTOTPAR or VASSPID values for each drug group were converted to %maxTOTPAR by division into the calculated maximum value [17 ]. The proportion of patients in each treatment group who achieved at least 50%maxTOTPAR was calculated using valid equations [18 (link),19 (link),20 (link)]. The number of patients with >50%maxTOTPAR was then used to calculate relative benefit and NNT for paracetamol plus codeine versus placebo. Relative benefit and relative risk estimates were calculated with 95% confidence intervals (CI) using a fixed effects model [21 (link)]. NNT with 95% confidence intervals was calculated by the method of Cook and Sackett [22 (link)]. A statistically significant difference from control was assumed when the 95% confidence interval of the relative benefit did not include 1. Confidence intervals of proportions were calculated according to Morris and Gardner [23 ]. Calculations were performed using Excel v 5.0 on a Power Macintosh G3. Simulations and calculations of probability were conducted as described in Moore et al, 1998 [11 (link)].

Drug-specific PIM statements were extracted from each of the nine criteria and entered into an Excel file. One author (JP) examined the selected criteria and created the summary table. If the criteria included a statement to avoid a medicine class, the statement was documented in the summary for medicines mentioned by name in other criteria. For example, the NORGEP-NH includes a statement about regular use of hypnotics. According to the Anatomical Therapeutic Chemical (ATC) classification system by the World Health Organization [28 ], the code for hypnotics and sedatives is N05C. Based on this international drug classification, the statement from NORGEP-NH was documented for drugs whose ATC code is N05C and those listed in other included criteria. Unclear classifications were discussed among the three authors (JP, JJ, EJ).
We did not consider the following kinds of PIM statements from the final table: (1) concurrent use of two or more drugs (e.g., warfarin combined with non-steroidal anti-inflammatory drugs (NSAIDs)), (2) PIMs and specific conditions (e.g., Angiotensin Receptor Blockers in patients with hyperpotassemia), (3) PIMs and restriction of treatment duration or dose, (4) PIMs with limited research evidence or experience among older people, and (5) anticholinergic medicines without a specific active substance. Not including a statement was related to the restrictions on the data. First, the statements requiring additional clinical information (e.g., diagnosis, renal insufficiency, dosage, treatment duration) were not applied since such details could not be captured from the national prescription register. Second, some of the included criteria (e.g., Meds75+ database, Beers criteria) contain a special category for medicines with specific caution (e.g. use with caution, present evidence or experience with use in older persons is vague). Overall, the comparison of criteria focused on identifying PIMs to avoid generally without considering additional clinical information. This research strategy collected a summary of 352 ATC codes considered as PIMs (see Additional file 1).
The summary was screened using both the Social Insurance Institution (SII) of Finland’s Medicinal Products Database and Finnish Medicines Agency’s FimeaWeb to exclude medicines not available in Finland. If the medicine was available on the market only in combination (e.g., codeine), the medicine was still included. In addition, if the medicine was available both as a single active substance and in combination (e.g., oxycodone), both ATC codes were included. Finally, after screening the summary, 172 ATC codes were considered as PIMs available on Finnish pharmaceutical market (see Additional file 1).

Exposure to opioids was captured using prescription information available in the pharmacy claims (e.g., medication name, fill date, days supplied). Opioid exposure was examined at monthly intervals from each person’s study entry date to their drop in health plan enrollment or end of study period, whichever came first. Individuals were included in the analysis per month if they had enrollment for that entire month. Opioid exposure was determined by an outpatient pharmacy fill for a product containing hydrocodone, oxycodone, tramadol, codeine, morphine, fentanyl, and “other”, which included hydromorphone, buprenorphine, propoxyphene, oxymorphone, methadone, dihydrocodeine, levorphanol tartrate, meperidine hydrochloride, opium, pentazocine, and tapentadol.
The timing of opioid exposure was based on the date of prescription and number of days supplied, which allowed for the determination of monthly exposure as binary (yes/no) and number of days supplied. To standardize the number of days supplied per month, the proportion of each month exposed was calculated as the days supplied divided by the number of days in that month. This study did not standardize doses across opioid types (e.g., oral morphine equivalents) given the variability in suggested conversion factors [24 (link)]. Further, it is unknown if the proportion of opioid prescriptions by type differs for adults with and without CP, and how variation in conversion factors could impact interpretations. Therefore, this study focused on measures of opioid exposure as exposed/not exposed, the number of days supplied, and the proportion of opioid prescriptions by type.

In this paper, we examined two outcomes, (1) experience of recurrent pain, measured by the question “Do you suffer from pain that occurs frequently?” (Yes/No), and (2) use of prescription opioids among those who responded “yes” to outcome 1, measured by the question “In the last 3 months, have you taken pain medications that require a prescription such as pain relievers that contain codeine or morphine (Fiorional, Tylex, Duramorf, Demerol, Durogesic, OxyContin, Codex, Percodan, Dimorf, Tramadol)?” (Yes/No). Due to a skip pattern in the questionnaire, we were not able to measure prescription opioid use in the full sample of participants, but only among those who reported pain based on question 1.

The following data were extracted from patient Egton Medical Information System (EMIS) records: anonymised ID, age, ethnicity, gender, GP practice code, GP partial postcode, name of opioid, dose and quantity prescribed, date prescription was added to patient record, most recent issue date, course status (past or current) and any reported problems linked to the opioid prescription. Liverpool CCG (LCCG) acted as the gatekeeper and obtained verbal consent from GP practices to share patient information. Sixty-two of the 88 GP (70.5%) practices located across LCCG agreed to share patient data. An extract report was uploaded onto EMIS web, the data was extracted and then saved onto a secure network in an Excel spreadsheet. The data was pre-processed using Microsoft Excel, after which 93,236 prescriptions written for 30,474 patients remained (see Fig 1).
All prescriptions were cross-referenced with the British National Formulary (BNF) and re-coded according to their active opioid ingredient. This resulted in 12 groups including: oxycodone, tramadol, matazinol, methadone, morphine, tapentadol, pethidine, fentanyl, codeine, buprenorphine, dihydrocodeine and hydromorphine. Opioids commonly indicated for cancer or drug dependence (including dextropropoxphene, diamorphine, alfentanil, coproxomol, galenphol, oxylan and pavacol) were excluded. Dosage instructions were recoded to facilitate calculation of MED; if missing, maximal possible daily dose provided by the BNF was used.

A Defined Daily Dose (DDD) for each prescription was calculated using the drug name and administration instructions; MED was calculated using DDD. Calculations for MEDs depended on the type of opioid prescribed and were computed using the equivalence parameters in Table 1, overseen by a Consultant Anaesthetist with extensive experience in opioid prescribing for CNCP (BF). The calculations needed to account for multiple daily opioid prescriptions that patients may take, whether or not they use the prescriptions concurrently. As a result, once MEDs were calculated for every prescription a new variable was created to calculate patients’ combined daily MED (MED sum) which reflects the total MED if they were to use all of their prescribed opioids. The purpose of this variable was to establish one potential total of MED for each patient, specifically for those with more than one prescription that may contribute to their daily morphine intake. However, it is clear that not all prescribed medication will be taken simultaneously, with patients choosing from a range of their prescribed medication according to the current severity of their pain. The new MED sum parameter was used to create an average MED variable, by dividing the MED sum by the total number of prescriptions for that patient, thus accounting for the multiple prescriptions that patients may receive. In summary, MED sum = the total potential MED for a patient based on all currently prescribed opioids and MED average = MED sum/number of currently prescribed opioids.
For example, a patient prescribed co-codamol (30/500; 4 x 2 tablets per day), buprenorphine (10ug/h; 1 patch per week) and morphine sulphate (10mg/5ml; 2.5ml x 6 per day) would have a DDD of 240mg Codeine (30mg morphine) from the co-codamol, 10ug/hour (30mg morphine) from the buprenorphine and 30mg morphine from the morphine sulphate giving a total MED of 90mg (MED sum = 90). A patient may not take all of these medicines concurrently so prescriptions were averaged to give a daily MED average of 90/3 = 30mg MED.
