Qualitative Evaluation of the Influence of Acute Oxaliplatin-Induced Peripheral Neuropathy on Quality of Life and Activities of Daily Life.

INTRODUCTION/AIMS: Oxaliplatin often causes acute or chronic peripheral neuropathy in patients with an intestinal or pancreatic tumor, but in-depth insights in its influence on quality of life (QoL) are lacking. We explored the influence of acute oxaliplatin-induced peripheral neuropathy (OIPN) on daily QoL in these patients. METHODS: We performed semistructured interviews with a purposive sample of patients receiving oxaliplatin and possibly experiencing acute OIPN. Interviews were audio-recorded, transcribed verbatim, and coded by two researchers. Data were analyzed by using the constant comparative method for content analysis with ATLAS.ti software. RESULTS: After nine patients, saturation took place. In total, 11 patients were interviewed. Four themes were extracted from the data: (1) adverse effects, (2) physical (un)well-being, (3) emotional aspects, and (4) treatment aspects. All participants were suffering from acute OIPN to a certain extent, leading to restrictions in daily activities such as household chores, but also to a decrease in mobility and independency. Other adverse effects such as general malaise and gastrointestinal side effects also influenced the participants' well-being, as did the diagnosis and prognosis of their disease. CONCLUSION: Acute OIPN, together with other side effects of chemotherapeutic treatment and the difficulties that come with the diagnosis of cancer and its prognosis, largely influences patients' daily QoL. Managing expectations (by patient education) seems important.

Multimodal analgesia practices for knee and hip arthroplasties in the Netherlands. A prospective observational study from the PAIN OUT registry.

INTRODUCTION: Different multimodal pain management strategies following total hip arthroplasty(THA) and total knee arthroplasty (TKA) surgery are used in clinical practice. The optimal pain management strategy, however, remains unclear. This study aims to evaluate the differences in perioperative multimodal pain management strategies for THA and TKA in the Netherlands, and studies the associations between patient- and therapy related factors and pain outcomes. METHODS: Data from the Dutch hospitals in the PAIN OUT network were used in this study. Demographic data, pain management strategy including perioperative medication use and anesthetic techniques were recorded and used in a multivariable regression analysis to study the association with maximum pain intensity, the duration of severe pain, pain interference in bed and postoperative nausea. RESULTS: In 343 hip arthroplasty patients and 301 knee arthroplasty patients in seven hospitals, respectively 28 and 35 different combinations of analgesic regimens were used. The number of different drugs prescribed was not related to postoperative pain intensity. Female sex, younger age and spinal anesthesia were associated with higher postoperative maximum pain scores (Numeric Rating Scale (NRS) > 5). Hip surgery and ketamine use were associated with lower postoperative pain scores. The use of non-steroidal anti-inflammatory drugs (NSAIDs) and gabapentinoids, higher age, higher body mass index (BMI) and male gender were associated with less postoperative nausea (NRS < 3). CONCLUSION: In conclusion, our study demonstrated a large diversity of analgesic strategies following total joint arthroplasties in the Netherlands. Although no ideal strategy was identified, the use of NSAIDs, ketamine and dexamethasone were associated with less pain and less side effects.
